This book explores new directions in the study of China’s borderlands. In addition to assessing the influential perspectives of other historians, it engages innovative approaches in the author’s own research. These studies probe regional accommodations, the intersections of borderland management, martial fortification, and imperial culture, as well as the role of governmental discourse in defining and preserving restive boundary regions. As the issue of China’s management of its borderlands grows more pressing, the work presents key information and insights into how that nation’s contested fringes have been governed in the past.
